Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the potential merits of a) making HMRC taxpayer data available to Electoral Registration Officers for the purposes of Automatic Voter Registration, and b) allowing people who update their address with HMRC to update their voter registration automatically at the same time.

The taxpayer information HM Revenue and Customs (HMRC) holds is subject to a strict statutory duty of confidentiality. HMRC will share taxpayer information however, where there is a lawful basis to do so and to support wider government objectives. In July 2025 the Ministry of Housing, Communities and Local Government (“MHCLG”) published its strategy for modern and secure elections with a focus on the effective and safe sharing of data to improve voter registration. HMRC has been working in collaboration with officials from MHCLG to identify data-enabled opportunities to support their objective of improving voter registration.
